When a Marked Point, whose underlying Object Point is 3D, is highlighted in the Source Photograph, the cursor and image in an oriented Destination will automatically jump to the expected location of the point. You can then find the point (which should be close by) and click on it to reference. Because the image moves also you can be zoomed and the image will re-center to the expected point location.
To use this mode, your Source and Destination Photographs must be oriented/processed. If this mode is on when one of the Source or Destination are not oriented then you will see no effect.
Auto-drive operates for Marked Points and Curve Marks only.
